I might be missing something obvious here, but I’m a bit confused with adding/editing shape keys.
I set my Basis key, this is fine, then I add another key (1) and move the parts I want to grow. This looks ok and I can move my slider from 0 to 1 to see the changes. Then I add another key (2) but I can’t edit from the new shape of key 1. If I move the parts of key 2 to match key 1 the vertices grow more in key 2.
I guess I’m looking for a way to lock in the changes on each key iteration of the animation, otherwise I’m always guessing from the Basis key.
